My mom's cat had 4 kittens. They are old enough to move to the farm, but they are still kittens. My question is, if I take them to the farm house, should I build a structure of some sort to keep them safe from aggressive animals that might attack them. There is no barn to turn them loose in. They'll simply be allowed to run around the house. I'll put food and water out for them each day, but they won't be allowed inside the house. Any suggestions? Thanks for the help.
